Cold acclimation induces distinctive changes in the chromatin state and transcript levels of COR genes in Cannabis sativa varieties with contrasting cold acclimation capacities.

Little is known about the capacity of Cannabis sativa to cold-acclimate and develop freezing tolerance. This study investigates the cold acclimation (CA) capacity of nine C. sativa varieties and the underlying genetic and epigenetic responses.

Transcriptome analysis of an mvp mutant reveals important changes in global gene expression and a role for methyl jasmonate in vernalization and flowering in wheat.

The einkorn wheat mutant mvp-1 (maintained vegetative phase 1) has a non-flowering phenotype caused by deletions including, but not limited to, the genes CYS, PHYC, and VRN1. However, the impact of these deletions on global gene expression is still unknown. Transcriptome analysis showed that these deletions caused the upregulation of several pathogenesis-related (PR) and jasmonate-responsive genes.

Comparative analysis of the cold acclimation and freezing tolerance capacities of seven diploid Brachypodium distachyon accessions.

Background And Aims: Cold is a major constraint for cereal cultivation under temperate climates. Winter-hardy plants interpret seasonal changes and can acquire the ability to resist sub-zero temperatures. This cold acclimation process is associated with physiological, biochemical and molecular alterations in cereals.

Cryopreservation of insulin-secreting INS832/13 cells using a wheat protein formulation.

Diabetes is a global epidemic that affects about 285million people worldwide. For severely-ill patients with type I diabetes, whole pancreas or islet transplantation is the only therapeutic option. Islet transplantation is hindered by the scarce supply of fresh functional islets and limitations in cryopreservation procedures.

Expression of vernalization responsive genes in wheat is associated with histone H3 trimethylation.

The transition to flowering in winter wheat requires prolonged exposure to low temperature, a process called vernalization. This process is regulated by a genetic pathway that involves at least three genes, Triticum aestivum VERNALIZATION 1 (TaVRN1), Triticum aestivum VERNALIZATION 2 (TaVRN2) and Triticum aestivum FLOWERING LOCUS T-like 1 (TaFT1). These genes regulate flowering by integrating environmental and developmental cues.

Comparative expression of five Lea Genes during wheat seed development and in response to abiotic stresses by real-time quantitative RT-PCR.

Gene expression profiles of group 2 (dehydrins) and group 4 Late embryogenesis abundant (Lea) genes in developing seeds of Triticum durum and T. aestivum and in coleoptiles and coleorhizae of T. durum seedlings were monitored by real-time quantitative RT-PCR.

[Image-guided neuroendoscopy].

Background And Purpose: By definition, image-guided neuroendoscopy is a connection between a neuroendoscope and a neuronavigational system creating a computer-guided instrument. Our objective was to adapt our rigid endoscope with our neuronavigation system to perform computer-guided endoscopy.

Methods And Results: The rigid neuroendoscope, equipped with light emitting diodes, was connected to the work station.

[Direct transnasal approach. Description and feasibility in 60 patients].

Background And Purpose: The direct transnasal approach is a less invasive approach to the sella turcica and represents an alternative to the sublabial transsphenoidal approach with minor oro-nasal complications. In this study, we describe this approach with emphasis on post-operative course.

Methods: We studied retrospectively 60 patients operated on consecutively by a transnasal approach between January 1996 and December 2000.
